Visited on Sunday without charging for some night pictures.
I plugged in for the picture, and confirmed that the live data on IchTankeStrom shows occupied even though no charging session was started. Which is good, as you know you cannot use the charger until that person unplugs.
I think they changed something with the contactless readers at some point, they are not angled the same. They also changed the text on the back of the chargers to put a smaller Fastned logo and the text saying the screen is on the other side.
